  1. IIRC it was used as a tweeter in some pro models.
  2. What can you tell me about Fortes

    you can also try listen the same degree off axis of the horns by using more toe out so that you are listening at the same angle off axis but on the opposite edge or side of the horn. This may open things up for you. Remember that the off axis of horn's output is where they have their worst frequency response and on axis is where the response generally best. I would suggest that the beaming and or edge related to that position is not necessarily the horn but rather more likely your system. Having had Forte and Forte ll along with Heresy ll and Heresy lll, CF3 and KLF20 the only ones I would describe as a little hot on axis are the Heresy ll (more so) and Heresy lll (less so) but that can be tamed with some damping and open cell foam. Running in a well balanced system these speakers do not hot have to be hot on axis. Setting up with an equilateral triangle makes for the very best use of your horns directionality and yields the smoothest frequency response with the least possible room interaction. While your present set up may be working more to your liking it is not optimum. The more different speaker positions you try out and listen too be they good or bad the more you will learn about your room and what will work there. Sometimes some very odd placements can yield very good results but a good reference is a logical place to start. I always start with an equilateral triangle so if you are sitting 10' back from the speaker they will be 10' apart CTC and each speaker will be 10' away from your head directly on axis then you can play with a tiny amount of toe in or out.
  3. Proper Ohm Tap for Chorus lls

    most of the tube amps which I have owned which gad multi tap output transformers sounded best running on the highest impedance tap. The reason is simple and it makes sense. The multi tap output is a consumer pacifier marketing gimmick to give the buyer the confidence to purchase the amp. It is not a very good idea here's why; lets say the amp has a 4 and 8 ohm set of taps and you choose to use the 4 ohm taps that means that fully half of your secondary winding (output side) is totally un loaded and flapping in the breeze as it were. Much better to load the full secondary and use the 8 ohm tap. The difference in available current will be very little.
  4. La Scala with Gold Threads in speaker grille

    Got to love that clear lacquer on Birch.
  5. Identify a speaker model and age

    the sticker says they are Chorus ll (CH2) way high, but way better than Forte ll.
  6. 1984 Cornwall with Plastic Mids?

    Could be a number of different things but smaller horns don't provide directivity control as low as larger ones do. A good large horn (with a good driver capable of the range) will always sound better than a good small horn. If the LaScala are old then they may well have issues and you are hearing that. Properly working LaScala don't sound honky or horn like, good horns don'e sound horn like. the fifteen inch woofer in a Cornwall run all the way up to the mid horn and they overlap it so yes the woofer had a great impact on the low mid. I expect you will sort thing out. Don't give up on your LaScala because the Cornwall's don't hold a candle to them in terms of efficiency and dynamics. The LaScala does require bass support if you want full bandwidth response. The bottom end response looks much like a Heresy does. Remember too that if your listening room is small you will get better integration with a smaller loudspeaker simply because you can get farther away from it giving it more distance to integrate and a two way can integrate over a shorter distance than a three way can. One of the reasons why two ways are so popular in near field monitoring situations. In any room a LaScala is going to protrude into the room much more than a Cornwall will. If you are happy with the Cornwall then life is good they are a very nice loudspeaker. If you want to stay with that three way format but want more then look to a Chorus ll and get a good amp with plenty of watts they can really impress when driven well and the improved larger mid horn is a definite step up. The slightly smaller Chorus with its pro woofer is the replacement of the Cornwall, The Chorus uses the same K600 mid horn as the Cornwall and the Chorus ll uses a newer designed larger hybrid Tractrix mid horn. With some power behind them they will not fail to impress. If you want to run small SET amps then stay with the Cornwall.
  7. Horn/tweeter Stopped Working

    First thing you need to do is to check the jumpers (between the woofer and the tweeter) on the back of the loudspeakers on the terminal cup, chances are the binding posts are loose and you simply have an intermittent jumper connection and that is likely why you lost a tweeter. Do that before you start pulling all your cables out making a mess and getting frustrated because if that is the issue then all that other stuff won't make any difference.
  8. Nice CW decorators

    Yep that's a nice clean looking room. Can't however understand why anybody would want to listen to their horns off axis like that where their response is in the toilet.
  9. 1984 Cornwall with Plastic Mids?

    larger horns provide directivity over a wider band meaning that they control their output polar patterns to a lower frequency. That means that a larger horn is what you want in a smaller room as it minimizes room interaction to a lower frequency. So I don't think it is because of the horn that you prefer your CW's I would suggest that their better bass is what you prefer. In any event as said what you like is the important thing and that's all that matters.
  10. 1984 Cornwall with Plastic Mids?

    K601 is going to be a much cleaner built and tighter geometry horn than the cast metal version. I would not trade a K601 for a K600. Same goes for the K701 when compared to the metal cast K700, the K701 embarrasses all the metal K700 I have seen.
  11. Duratex or ?

    use a sealer/primer first after your surface prep.The sealer will stop paint from sucking into the wood. Remember the prep time that you spend will determine the ultimate quality of your finish. Pick a nice color for the inside.
  12. Flea Watt Amp Recommendations

    flea watt is generally less than a watt. if you have true high efficiency loudspeakers, you can do a lot with a watt but a SE 45 or a 2A3 is even better. And you can make a lot of good bass too.
  13. I'm a Believer! (another cable story)

    get some tea cups, juice glasses or coffee mugs and you will know for yourself. I have tried this and yes you can hear what they do. Ceramic or glass will sound better than plastics so far as I know from listening.
  14. RP28F replacement spikes

    most are the standard 1/4"-20 threads per inch. that's what all your furniture glides are. ramset studs work the beds case hardened steel they are designed to penetrate up to 1/4" steel they are perfect, much better than large cone type spikes. the spike has to penetrate the jute backing on your carpet to get to the wood floor underneath and large points cannot do that. As a result with cones you end up floating up on the jute. hope this helps see link below. http://www.ramset.ca/product/39/threaded-stud-pins
  15. Raising P.S. Capacitance

    need to keep inrush current in mind at turn on if you are going to add a lot of filtering to the supply.
